Yep I know their rep but trust me I measured him 3" in body wit tail 4". An the first fish he took out was that beautiful Aro. I still think this deserves to be a sticky only because I really didn't think the devil would eat a fish twice his size. An that was a underestimation on my part, but one I think many might make. Plus I think he tagged the Aro cause he was a mid to top water fish unlike my other cats. My Gulpers never scavenge or even go near the bottom of my tank except to rest. Hence all my other cats have been safe from his predation. Like I said I got 2 2" woodcats, and a 2" megalodoras, as well as some other 6" cats that have lived with the Gulper peacefully. Heck one of the reasons I started hand feeding the Gulpers is cause they had trouble eatin feeders,krill an worms(etc.) except from my hand. Even on planetcatfish they say a Gulper should be fine with fish twice it's size but peaceful enough not to hurt the Gulper. An this was what I thought when mixin the two fish. Thanx for the sympathy tho the Aro was beautiful and a great addition to my tank.
